LIQUID-DISIPIJ-NSING DEVICE.

J Application fi1ed April 26, 1327.

'lhis invenuion relates t liquid dispensing devices und 1no1e especially to devices f01' use in lubricating tl1e sp1ings, cl1assis, and the lil e of an autom obile.

Heretofnre, it has been customary t0 sell spring lubricating 0il and the like in C011- i-ainc=rs 01 suitable size to be held in tl1e hand und 110 furnish them with a nozzle to be attacl1cd so the container when it is desired t0 apply be 0il 01' the like. lVith such an arrangement it is n0t practical t0 0il tlse portions 01": tl1e springs, spring shackles, and othe1yparts arranged unde1 the body of the ca1 as l:l1e containe1 cannot be arranged al ove tl1e nozzle because of the limited space between Ehe Part t0 be lubricated and the l udy 0f the car and 110 means are provided 10 force oil upwardly through the nozZle.

An object 0f this invention is a container f0i' lubricants 01 the like pfovided with meai1s f01 dispensing th'e contents thereof by 1ue-ans 01' compressed air, which means serves as a handle f01' supporting the container and by means of which the stream of oil dispensed from the containor may be directed as desired.

Accoi'ding t0 this invention a tube isattached to th0 upper portion of the container und is provided with means t0 cooperate Wiih 1 he chuck 01: an air hose 01 the fitting 011 tire pump so that a stream 0.f air may be directed therethrough. A finger-grip is mountecl 0n the tube by means of which the eud 016 the tube may be pressed into the chuck of an air hose arranged in t-he palm 0f ihe operators hand. A second tube ex tends int0 the container and has one end so arranged tl1at the stream of air discharged from the first tube produces suction in the second tube. A nozzle may be provided f0r clirecting the stream of air and liquid produced by the fiow of air through the first tube.

The tubes and the nozzle may be connected directly 150 alle container 01 may be connected to a cap which may either be the original cap f0r the container o1 a cap provided to replace the original cap. In the event that the tubes and nozzle are directly attached t0 the container the latter Will have n0 cap but means a1te provided'to vent tl1e container. Likewise, the cap is provided with a vent. When it is desired t0 use devices of this character the chuck 01? the' air hose is a1- ranged in the palm of the band and the end 0f the first tube inserted therein. Suflicient Seria1 N0. 186,620

pressu1e 1 0 opeu die chuul; is applied by means 01? the Fingers around the grip. Th

container is suppurted by tl1e tube und als it is not 0f n 1uch weight can easily be moved about and easily arranged in proper positi0n t0 direct a spray of liquid wherewar desired. Vith such device Ehe obherwise inaccessible parts 0f an automobile may be easily gotten at as tl1e liquid strezun may 110 directed as desi1ed. It constitutes a very handy and convenient device which can be used wherever cmnpressed air is available und as the container is connected directly t0 l1e ai1 tube the1e is 110 trouble witl1 tubes leading froxn the c ntainer t0 the air tube und the 0nly thing that has t0 b0 lookcd out f01' is the 2111 l10s6.

Otl1er 0bjyectsg1ovel :features und advantig0s 01 this invention Will bc appareu fron1 tl1e following 'specilication and accompanying dra'wing, wherein Fig. 1 is a perspective view of tl1e device mubodying tl1e invention,

Fig'. 2 is a longitudinal section through such dovice, und,

Fig. 3 is a pa1tial section 0f a 1nodified f01n1.

10 designates a preferably metal can o1 concainer Wlii :li is provided witl1 a neck 11, Ehe top of which is cl0sed. Mounted 011 the t0p 013 the nach 11 is an air tube 12 having a threaded end 18 wl1ich 1nay be inserted in tl1e chuck 0f an ai1r hose 01' 1 0 whicl1 may be screwed tl1e air tube 0f a tire pump. 141 is the chucl 0f an air hose afnd is shown in positionto receive the end 13 of the tube 12. A finger-grip 15 is Provided 011 the tube 12 by means 0:E Wlii0h the end 13 0 5 t-he latter may be forced into the chuel; 11 to open tl1e same and permit a stream 0f air t0 flow through ahe +ube 12.

A second tube 16 extends tfr01n tl1e top 0f t-l1e necl: 11 into container 10, ehe end 0f this tube being anjacent thc end 0f tl1e air tube 12 so tl1at tl1e stream cf air fro1n the tube 12 is directcd across the end 0f the tube 16 to produce suction therein. A ball check valve may bo provided ab the bottom 0tf tl1e tube 16 t0 prevent 110W 0f liquid fl0111 the tube int0 the can 10. A nozzle 18 is threaded into a sockot 10 attaclied t0 tl1e neck 11 in alinemcnt with the ond 0f the tube 12. In the necl 11 is provided a vent hole 20 which is closed by a seal 21 01 the lil:e to be pulled ofl when tl1e device is first put into use. The uppor end of the tube 16 1nay be closed by a soft metal seal Which is to be cut oii' or otherwise ren1oved at the sa1ne tin1e as the seal 21 is removed. The container may be lilled with liquid bcfore the tiibe 16 is inserted and with the vent hole 20 open. The tuhe 16 may then be soldered to izhe nontainer and sealed andthe seal 91 applied Tho vent hole 20 is This provides a practieally non-refillable can for lubricating oil 110 be sprayed 011 the springs and other inaccessible parts of automobiles, liquid polisli for automobile bodies, und ior liquid for 1nany other uses. lt ensur es delivery of the original contents to Ehe purehaser' and prevents the can from being refilled Witli other liquids without mutilation aifter the original content-s liave been dispensed. It also provides an easy and eflioient device for applying liquids where d'esi1ed permits conurol of the application o f t'he liquids and prevents waste h directins;

the liquid in a fine spray where desired Wii'li 'penetrat1ng force.

In t-he iiiodiiic-ation disclosed in Fiat 3, lhe neck 11 of the can 10 is open and screw threadedto receive a cap. The air tube 12" is mounted'on a cap siiitable to hereceived by the neck 10 as is the suction tube 16. The tube 12 is provided with a threaded end 18 .and a fingiergrip 15, SllIlllill to those diselosed in the modification presented in Figs.

1 and 2. The directing nozzle is not shown is closed with a soft metal seal as described in connect-ioi1 with Figs. 1 and 2. 'lhe eap is designed With a ortion to be punched out to form a ve1it.

Either mod1fica1on may be used m counect'ion wiih an air hOs, the hucl; of which 1s held 111 ihe palm ol the band wit-h the fingers overly1ng the gr1p or in connection v rvith .tl1e.-air iuhe of a tire pump or ehe like.

When thus held, ehe device may be easily lii'ted .and located adjacentihe Parts to be lubr1cated and ihe strea1n of liquid acrurately directerl Wl1en used in connection with i-he Chuck oi an air h0se the strea1n o'f liquid iiiay l)0 controlledby ehe pressure applied leihe finger grip. Niuh such device lhe ordinarily inaecessible partS oi an automobile 1nay be easily, quieklyand thoroughly located.

Although Ehe above description of the de vice has had more fo do witli its use in Connection Wll'll lubrican'ts, it is apparent that it 1nay be made use of in connection Wiili any suit-able o1 desired liquid.

lVhat I clai1n -as new -and desire to secure by Letters Patent -oi the Uniiod States is;

l. A device of the characier described compr1s1ng a closed uiiii;ar conta1ner hav- 1ng a pa1r of'orifices normall}; closed by soft metal sezils, a discharge tub depei1ding i"i'0iii one orifice into said contai'ner aiid he o'lher orifice providing a Veiit f0r ehe container and an air cube rigidly conneoted co said Container at one end aiid posiionecl 'to direct a current oi air across t-he liquid discharge oiifice.

2. A dei*ice of the charaeer desoribed C0iii prisiiig a closed unitary container having a pair of orifices normally closed hy soft 1netal seals, a discharge cube depending lr0in o1'1e orifi'ce into said coniainer and the other. orifice providing a vcnt for the con iainer anda finger grip 011 said air tuhe by 1nea1is otf Wliich th e i'reo end ihereof may be brought into operative relai;i0nship to an air chuek and the Container be liited and moved to direct -t-he discharged liquid,

In testi1nony wl1ereol, I have signed In nanie to ihis specification.
